Steven Winter Associates, Inc. (SWA) hereby proposes to undertake research to develop a self-configuring residential conditioned air zoning system for low load energy homes. The Phase I prototype will feature zone nodes and a master controller. The zone nodes will measure and wirelessly report environmental conditions to the central controller, and modulate a damper based on commands received from ...

New Generation Access Control (NGAC)—because of its “neutrality by design”—represents the most effective and scalable approach for deploying “smart” access control and consent solutions in large dynamic scenarios. NGAC however presents with its own problems: (1) it has miniscule recognition and uptake in the workplace, (2) it is unusable by non-technical policy officers and (3) its doc ...

A Multimodal Acoustic Tool for Inline Pipe Inspection 3/19/2018 The US energy transport pipeline system is a longstanding distribution network with most of its still standing pipes being installed between the 1950s–1970s. Due to degradation mechanisms, such as embrittlement, capable of causing a two-fold reduction in fracture toughness, pipe rupture is a major risk. Current nondestructive ins ...

Proposal title: Rapid Assessment of Air Void System in Fresh Concrete Water expansion during freeze-thaw cycles can cause deterioration in concrete, leading to scaling, cracking, and crumbling over a period of years. Resistance to this damage is achieved with a system of voids formed by adding surfactants to the fresh concrete to stabilize air bubbles naturally entrained during mixing. The volume ...

Proposal title: Broken Rail Detection from Flashing Rear End Device Broken rails are a common cause of mainline derailments and a particular concern given the increasing use of our rail system for passenger traffic and petroleum products. The progressive nature of the defects provides an opportunity for early detection of cracks before they become significant enough to cause a derailment. Unfortu ...

Coating disbond on buried pipelines contineus to be a major problem world-wide. Disbonds left unrepaired promote both corrosion and stress-corrosion cracking, which are much more costly to repair. Improved inspection technology is currently needed to detect and characterize disbonds. HD Laboratories, Inc. proposes to refine and test a novel method of detecting and assessing coating disbonds and ...

Homeland Security/First Responder networks require increased bandwidth and reliable connectivity. Future networks such as Project SAFECOM may deploy software-defined radios (SDR) compatible with Joint Tactical Radio System (JTRS) Software Communications Architecture (SCA). We leverage our SCA compatible, high assurance ¿Smart Radio¿ prototype being developed under an AFRL sponsored Phase II ...

For more than three decades, transportation planners have relied on survey data collected specifically for the development of travel forecasting models, which are expensive to collect and maintain on an ongoing basis. There is a plethora of data collected for other reasons that could potentially support transportation planning which is becoming more accessible through technological advances. Use ...

LABORATORY EXPERIMENTS CONDUCTED IN A STRATIFIED TOW TANK ARE PROPOSED TO CHARACTERIZE VORTEX WAKES UNDER THE INFLUENCE OF ATOMOSPHERIC DISTURBANCE. FLOW RESEARCH HAS DEVELOPED INNOVATIVE TECHNIQUES FOR STRATIFYING THE FLUID IN THE TANK, GENERATING A CURRENT SHEAR AND CREATING AMBIENTTURBULENCE WITH GOOD CONTROL. SUCH CAPABILITIES WOULD FACILITATE THE ISOLATION OF THE EFFECTS OF THE DISTURBANCE S ...

THE PHASE I RESEARCH IS INTENDEDTO DEMONSTRATE THE BASIC FEASIBILITY OF CONSTRUCTING AND OPTIMIZING A NEW MAGNETO-OPTIC 'SANDWICH' DEVICE INTENDED FOR DIRECT VISUALIZATION OF FLAWSIN FERROUS MATERIALS (STEEL) IN A MARINE ENVIRONMENT. THE DEVICE IS BASED IN THE PROPERTY OF SOME MAGNETO-OPTIC GARNETFILMS TO ROTATE THE PLANES OF POLARIZATION OF AN INCIDENT, LINEARLY POLARIZED LIGHT WAVE (FARADAY MAGN ...
